Wakana has spent every summer vacation on his own...until now! With a friend like Marin at his side, he's about to get a taste of everything summer has to offer and more—the pool, fireworks, extra homework…and of course, cosplay!

Now that she's crossed off bronzed fighter Veronica-tya from her to-do list, Marin has set her sights on a succubus from one of her favorite manga series! But when she picks out a questionable location for the photo shoot, Wakana's the one about to be left red in the face and hot under the collar!
